Description

Beeper formula digital coding sea bar the tinkle of bells pager apparatus

The utility model relates to a kind of pager apparatus, concrete a kind of radio-paging sea bar the tinkle of bells that is meant, the digital coding teleseme of the information that provides that a fish snapped at the bait.

At present, fishing uses that a fish snapped at the bait, and teleseme is to be fixed with small bell on fishing rod or fishing line, rocks small bell after a fish snapped at the bait and causes the tinkle of bells, because a little less than the tinkle of bells, the fisherman must be movable in the earshot scope, can not do other thing away from fishing rod, brings inconvenience like this.

The purpose of this utility model provides a kind of beeper formula digital coding sea bar the tinkle of bells pager apparatus, and it can accurately receive the information that a fish snapped at the bait.

The technical solution of the utility model is achieved in that

Beeper formula digital coding sea bar the tinkle of bells pager apparatus, by extra large bar bell, emission main frame and receiver are formed, sea bar bell is fixed on the extra large bar, the emission main frame is placed on 10 meters on bar off sea with interior a certain place, receiver is designed to the beeper formula and carries on the fishing person, the emission main frame is by microphone, filter circuit, amplifying circuit, decoding circuit, switching circuit, coding circuit, oscillatory modulation circuit, high-frequency amplifier circuit and battery are formed, receiver is by tuning circuit, high-frequency amplifier circuit, mixting circuit, oscillating circuit, inspection is filter circuit frequently, low-frequency amplifier circuit, shaping circuit, the digital decoding circuit, the chimes of doom source circuit, promote circuit, loudspeaker are formed, extra large bar bell shaken when ringing when a fish snapped at the bait, the tinkle of bells information by the microphone of emission on the main frame by by R5～R8, C12, C13, the second order high pass active filter circuit frequency-selecting that IC2 constitutes is amplified, again through IC3, after the amplifying circuit that R9～R13 forms amplifies, send into IC4, when the frequency of extra large bar the tinkle of bells equals IC4 just, C17, when frequency f o is levied at the center of the decoding circuit that R15 forms, IC4 becomes low level by high level, the LED conducting, triode T3 base stage has enough bias currents to make the complete conducting of T3 thus, the digital coding circuit is given in the conducting of T3, oscillatory modulation circuit, power supplies such as high frequency amplification emissioning circuit make their work: IC1 at first, SW-DIPB8, the coding circuit that R3 forms, compile out sign indicating number back conversion bunchiness shape signal according to the SW-DIPB8 state, insert the base stage of T1 by 18 pin of IC1, will be by T1, R2, C3～C7, L4, after the oscillator signal modulation that the high-frequency generator that L5 forms produces, modulated signal is sent into the T2 base stage by C2, again by T2, R1, L1～L3, C0, the high frequency amplification emissioning circuit that C2 forms, amplifying the back goes out to spatial emission, receiver receives the signal that the emission main frame is sent by antenna, through T1, T2, R1～R5, the high-frequency amplifier circuit that C1～C3 forms and by T3, R6～R9, C5, C6, L21, the superregenerative detection circuit that D1 forms, again via IC1:B, IC1:A, after the shaping amplification circuit that R12～R21 forms is handled, send into 14 pin of IC2, through IC2 digital decoder confirmation code, confirm the SW-DIPB8 state of receiver and the SW-DIPB8 state consistency of transmitter, 17 pin of IC2 become low level by high level, IC3 thus, T4, SP, R24～R29, C11～C13, D2～D5, the chimes of doom source circuit that LED forms is activated, send chimes of doom by loudspeaker, LED also flashes simultaneously, thereby the information that a fish snapped at the bait is communicated to the fishing people.

Because the utility model is provided with emission main frame and receiver, therefore it can accurately receive the information that a fish snapped at the bait, receiver is designed to the beeper formula in addition, easy to carry, the fishing people can be movable arbitrarily in 500 meters scopes of the extra large bar of distance, especially hook hangs down at night, can in time wake the fishing people that sleep is had a rest, in addition, this device adopts frequency-selective digital coding and decoding (100,000-1,500 ten thousand) transceiving technology, has the call distance, and is separate between non-directional and a plurality of extra large bar telesemes, strong interference immunity, high reliability features.
